WEBVTT 0 00:00.060 --> 00:01.170 In previous lessons, 1 00:01.200 --> 00:05.700 we completed our automated birthday wisher Python project 2 00:06.000 --> 00:10.110 and also the motivational quotes on Monday's Python project. 3 00:10.620 --> 00:11.700 But at the moment, 4 00:11.700 --> 00:16.700 you'll notice that this code is only going to work to continuously check to see 5 00:17.250 --> 00:20.970 which day it is currently, compare it against the birthdays, 6 00:21.300 --> 00:22.710 and then run the code 7 00:23.070 --> 00:26.610 if this code is actually running constantly in the background. 8 00:27.210 --> 00:30.990 Now you could of course, open up your project in PyCharm, 9 00:31.050 --> 00:35.730 hit run every single day and make sure that it works, 10 00:36.000 --> 00:39.840 but that's actually more effort than wishing somebody happy birthday manually. 11 00:40.380 --> 00:42.330 So what do we do instead? Well, 12 00:42.330 --> 00:47.330 we want some sort of way where we can host our code in the cloud and run our code 13 00:49.290 --> 00:50.670 every single day. 14 00:51.390 --> 00:55.380 So one way of doing that is using a service called Python anywhere, 15 00:55.830 --> 01:00.270 and they have a free tier where we can do exactly that without having to pay 16 01:00.270 --> 01:03.030 anything. Head over to python 17 01:03.030 --> 01:07.020 anywhere.com and go ahead and sign up for a new account. 18 01:07.830 --> 01:09.960 Now, once you've signed up and signed in, 19 01:10.230 --> 01:13.710 then you want to go ahead and start adding some files. 20 01:14.250 --> 01:16.320 Head over to the files tab right here 21 01:16.740 --> 01:21.740 and we're going to upload the files that's currently inside our birthday wisher 22 01:22.080 --> 01:26.310 project. So that's our main.y, our birthdays.csv, 23 01:27.480 --> 01:29.640 and also our letter templates. 24 01:30.150 --> 01:34.530 Now we want our letter templates to be inside a folder, so we're going to 25 01:34.530 --> 01:38.340 create a new directory called letter_templates. 26 01:38.760 --> 01:40.470 Make sure there's no typos there. 27 01:41.130 --> 01:45.360 And then inside this directory is where we're going to upload these three files. 28 01:45.840 --> 01:47.850 So letter 1, 2 and 3. 29 01:48.870 --> 01:53.700 So now we've got our letters inside hom/AppBrewery/letter_ 30 01:53.700 --> 01:55.980 templates, and inside AppBrewery 31 01:55.980 --> 01:58.740 we've got our birthdays.csv and our main.py. 32 01:59.400 --> 02:04.400 So now we're going to go into our console and we're going to create a new bash 33 02:05.430 --> 02:08.280 console. So we're going to click on this link right here, 34 02:09.570 --> 02:13.470 and then once all of that's loaded and you see this dollar sign right here, 35 02:13.740 --> 02:17.550 we're going to type python3 main.py. 36 02:18.960 --> 02:23.820 Now you might see this error right here, the SMTP authentication error. 37 02:24.360 --> 02:29.360 And this is something that happens because our Python program is trying to log 38 02:29.370 --> 02:33.510 into our email, and our email provider in this case, 39 02:33.540 --> 02:38.540 it's Google, is actually blocking it. So we can copy this URL and you can see it 40 02:39.510 --> 02:40.590 ends right here 41 02:40.590 --> 02:45.590 cause there's a space there, and we can paste it into the address bar and it 42 02:45.930 --> 02:47.220 takes us to this problem. 43 02:47.400 --> 02:52.200 I can't sign into my email client, and this is essentially what our Python code 44 02:52.200 --> 02:53.033 is trying to do. 45 02:53.400 --> 02:58.400 So what we need to do is click on this link to display the unlock capture, we 46 02:58.830 --> 03:03.670 click continue, and it's now enabled our code to sign in again. 47 03:04.120 --> 03:08.830 So we have to go back and type in exactly the same as we did before, python3 48 03:09.190 --> 03:10.120 main.py. 49 03:11.050 --> 03:14.980 But this time it should complete without giving us any errors 50 03:15.280 --> 03:19.000 and it does that by showing us the dollar sign again and our prompt. 51 03:19.570 --> 03:22.600 And now if I head back into my email, 52 03:22.810 --> 03:27.810 you can see that this email was actually sent because the code was initiated 53 03:29.290 --> 03:33.340 inside Pythonanywhere. So going back to our Python 54 03:33.340 --> 03:34.570 anywhere dashboard, 55 03:35.080 --> 03:39.040 we can go to the task section to actually schedule 56 03:39.280 --> 03:43.210 a task to run. Now to set up a scheduled task, 57 03:43.270 --> 03:46.930 we're going to type the same command that we did in the console 58 03:47.170 --> 03:49.870 which is python3 main.py. 59 03:50.560 --> 03:53.590 And then we're going to schedule this at a particular time. 60 03:54.010 --> 03:56.650 And the server time is based on UTC. 61 03:57.160 --> 04:01.180 So you can take a look at the current time in UTC 62 04:01.210 --> 04:03.790 by typing in UTC now into Google 63 04:04.120 --> 04:06.310 and you can see right now it's 12:09. 64 04:06.910 --> 04:10.900 So if I go ahead and schedule this for 12:10 65 04:11.440 --> 04:13.030 and I hit create, 66 04:13.540 --> 04:17.200 then at the time when this particular time hits, 67 04:17.470 --> 04:21.970 when it becomes 12:10, then our command should be run 68 04:22.300 --> 04:26.560 and we should see a happy birthday email show up in our testing Gmail account. 69 04:27.460 --> 04:30.970 So right now UTC has just gone to 12:10. 70 04:31.720 --> 04:34.810 And so if we wait for this schedule task, 71 04:35.080 --> 04:40.080 we can click on this button to view the task log and you do have to be quite 72 04:41.530 --> 04:46.530 patient because sometimes it might take a while before that task actually gets 73 04:46.810 --> 04:51.640 executed. So just keep checking the task log until you see this happen. 74 04:51.940 --> 04:56.320 Completed task at 12:10:56, o at the end of that minute. 75 04:56.710 --> 05:01.630 Took 16.92 seconds return code was zero, which means it was successful. 76 05:02.110 --> 05:07.110 And now we can see that email show up in our Gmail account and this was 77 05:07.480 --> 05:11.770 completely automated and it was done by Python anywhere. 78 05:12.160 --> 05:16.210 So now if we have that code running in the background every day, 79 05:16.240 --> 05:21.010 you can get it to run that code at this particular time or another time of your 80 05:21.010 --> 05:23.440 choosing in fact. If you're not testing it, 81 05:23.530 --> 05:28.030 you can actually get it to run much earlier. Let's say maybe seven o'clock UTC. 82 05:28.930 --> 05:31.180 Then it'll send the email out in the morning. 83 05:31.780 --> 05:36.760 And every day it's going to check whose birthday it is in your birthday CSV 84 05:36.850 --> 05:40.210 and then send an email to them and do all of that fancy stuff 85 05:40.330 --> 05:45.330 using what we did with Python. Python anywhere has really good forums for help 86 05:46.210 --> 05:48.910 and advice. And on the free tier, 87 05:48.940 --> 05:53.830 you can only schedule one task to run, so one particular code base. 88 05:54.190 --> 05:57.220 Now I don't work for them and I have no relations to them, 89 05:57.610 --> 06:02.050 but I find it really helpful to have a really simple way of getting my Python 90 06:02.050 --> 06:05.260 scripts to run everyday at a particular time. 91 06:05.500 --> 06:09.430 So have a look at that and you can use it if you find it helpful as well.
